Nine species of the genera Nucula Lamarck, 1799, Ennucula Iredale, 1931, and Brevinucula Thiele, 1934, are here recorded from southern Africa and Mozambique. The sole Mozambican species is Nucula (Lamellinucula) semen Thiele, 1931, which occurs also in Durban Bay sediments dating from the mid-­Holocene or perhaps late Quaternary. New species: Nucula (Nucula) planiculmen, N. (N.) subluxa, N. (Lamellinucula) rhytidopleura; Ennucula oliva. Revised status: Nucula (Lamellinucula) sculpturata Sowerby, 1904, for N. pulchra auct. ( N. pulchra Hinds, 1843, is a nomen dubium). New synonym: Nucula fragilis Boshoff, 1968 = Nucula [= Ennucula] fragilis Thiele, 1931. Types figured: Lectotype (here designated) of Nucula fragilis Thiele, 1931, holotype of N. aequalitas Barnard, 1964. Type localities corrected: N. (L.) sculpturata, N. (L.) irregularis Sowerby, 1904 Development: Nucula planiculmen and N. subluxa are incubatory.
